Warnings that are going to the journal should be not translated:
they're not user visible, and translating them would just make
bug reporting harder (as now the developers need to understand
what the warning is saying)
https://bugzilla.gnome.org/show_bug.cgi?id=707897
Switching meta/util.h to gi18n.h was wrong, mutter is a library
and needs gi18n-lib.h, but that cannot be included from a public
header (since it depends on config.h or command line options),
so split util.h into a public and a private part.
https://bugzilla.gnome.org/show_bug.cgi?id=707897
To allow other clients (gnome-session, gnome-settings-daemon)
to monitor user activity, introduce a DBus interface for the
idle monitor inside mutter.
https://bugzilla.gnome.org/show_bug.cgi?id=706005
When running as a wayland compositor, we can't use the xserver's
IDLETIME, because that's updated only in response to X events.
But we have all the events ourselves, so we can just run the timer
in process.
https://bugzilla.gnome.org/show_bug.cgi?id=706005
We can't use the X11 stage window, if clutter is not using the X11
backend (and even if it was, it would be bogus when the xwayland
server is not the one clutter is talking to). Instead, we introduce
the concept of "focus type", which we use to differentiate the
various meanings of None in the focus_xwindow field.
https://bugzilla.gnome.org/show_bug.cgi?id=706364
Under X, we need to use XFixes to watch the cursor changing, while
on wayland, we're in charge of setting and painting the cursor.
MetaCursorTracker provides the abstraction layer for gnome-shell,
which can thus drop ShellXFixesCursor. In the future, it may grow
the ability to watch for pointer position too, especially if
CursorEvents are added to the next version of XInput2, and thus
it would also replace the PointerWatcher we use for gnome-shell's
magnifier.
https://bugzilla.gnome.org/show_bug.cgi?id=705911
Now MonitorManager does its own handling of XRandR events, which
means we no longer handle ConfigureNotify on the root window.
MetaScreen reacts to MonitorManager::monitor-changed and updates
its internal state, including the new size.
This paves the way for doing display configuration using only
the dummy backend, which would allow testing wl_output interfaces.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
The previous code was leaving focus fields dirty in MetaWaylandPointer
and MetaWaylandKeyboard at time (which could crash the X server
because of invalid object IDs)
The new code is more tighly integrated in the normal X11 code
for handling keyboard focus (meaning that the core idea of input
focus is also correct now), so that meta_window_unmanage() can
do the right thing. As a side benefit, clicking on wayland clients
now unfocus X11 clients.
For the mouse focus, we need to clear the surface pointer when
the metawindowactor is destroyed (even if the actual actor is
kept alive for effects), so that a repick finds a different pointer
focus.
https://bugzilla.gnome.org/show_bug.cgi?id=705859
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.
The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.

This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.
This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.
TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.
Note: At this point no input is supported

We now track whether a window has an input shape specified via the X
Shape extension. Intersecting that with the bounding shape (as required
by the X Shape extension) we use the resulting rectangles to paint
window silhouettes when picking. As well as improving the correctness of
picking this should also be much more efficient because typically when
only picking solid rectangles then the need to actually render and issue
a read_pixels request can be optimized away and instead the picking is
done on the cpu.
gnome-shell needs to know whether the stage window is focused so
it can synchronize between stage window focus and Clutter key actor
focus. Track all X windows, even those without MetaWindows, when
tracking the focus window, and add a compositor-level API to determine
when the stage is focused.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
When we set the input focus, we first set the predicted window,
and then try to process focus events. But as XI_FocusOut on the
existing window comes before XI_FocusIn on the new window, we'll
see the focus out on the old window and think the focus is going
to nothing, which makes mutter think the prediction failed.
This didn't really matter as nothing paid attention to the focus
window changing, but with gnome-shell's focus rework, we'll try
and drop keyboard focus in events like these.
Fix this by making sure that we ignore focus window changes of our
own cause when updating the focus window field, by ignoring all
focus events that have a serial the same as the focus request or
lower. Note that if mutter doens't make any requests after the
focus request, this could be racy, as another client could steal
the focus, but mutter would ignore it as the serial was the same.
Bump the serial by making a dummy ChangeProperty request to a
mutter-controlled window in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=701017
This will make it possible to implement input source switching in
gnome-shell using the popular modifiers-only keybinding that's
implemented on the X server through an XKB option.
https://bugzilla.gnome.org/show_bug.cgi?id=697002
gnome-shell has traditionally just called XSetInputFocus when wanting to
set the input focus to the stage window, but this might cause strange,
hard-to-reproduce bugs because of an interference with mutter's focus
prediction. Add API to allow gnome-shell to focus the stage window that
also updates mutter's internal focus prediction state.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
If an app pops up an OR window and sets input focus to it, like
Steam does, we'll think the focus window is null, causing us to
think the app is not focused.
OR windows should not be special if they get input focus, where
the input focus would be set to NULL. Instead, the window should
be marked as focused.
https://bugzilla.gnome.org/show_bug.cgi?id=647706
Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.
Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).
https://bugzilla.gnome.org/show_bug.cgi?id=647706
Previously, we were handling failure to respond to _NET_WM_SYNC_REQUEST
in the code path for throttling motion events. But this meant that
if a window didn't respond to _NET_WM_SYNC_REQUEST and there were no
motion events - for a keyboard resize, or after the end of the grab
operation - it would end up in a stuck state.
Use a separate per-window timeout to reliably catch the failure to respond
to _NET_WM_SYNC_REQUEST.
https://bugzilla.gnome.org/show_bug.cgi?id=694046
During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other
processes to make use of it, gnome-shell will expose a simple
grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.
https://bugzilla.gnome.org/show_bug.cgi?id=643111
meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).
Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.
This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.
https://bugzilla.gnome.org/show_bug.cgi?id=688716
Use XSyncSetPriority() to prioritize the compositor above applications
for X server priority. In practice, this makes little difference because
the Xorg "smart scheduler" will schedule in a single application for
time slices that exceed the frame drawing time, but it's theoretically
right and might make a difference if the X server scheduler is improved.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,
use that as a signal that the applications wants an extended behavior
where it can update the counter as well as the window manager. If the
application updates the counter to an odd value, updates of the
window are frozen until the counter is updated again to an even value.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Instead of creating a new alarm each time we resize a window
interactively, create an alarm the first time we resize a window
and keep it around permanently until we unmanage the window.
Doing it this way will be useful when we allow the application to
spontaneously generate sync request updates to indicate
frames it is drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
As the hash table no longer stores only window IDs, we should rename it so
that we make sure to check if something is actually a window before using it
as a window.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
XInput 2.3 adds support for "barrier events", which let us know when
a pointer barrier has been hit, and when the pointer has stopped
hitting the barrier, and lets us "release" the barrier, temporarily
letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"
against the bottom of the screen, or stopping the pointer on monitor
edges while dragging slowly for increased edge precision.
This commit should allow graceful fallback if servers with
XInput 2.3 aren't supported.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
We want to put barrier wrappers in mutter, which requre XFixes 5.0.
XFixes 5.0 was released in March, 2011, which should be old enough
to mandate support for.

As calling XIGrabDevice multiple times will change it, just
drop the XChangeActivePointerGrab path and just go down the
XIGrabPointer path always.

It's unlikely that we'll ever want to support multiple pointer
devices. Multiple keyboard devices may become useful in the future,
but for now, only care about the core keyboard.
https://bugzilla.gnome.org/show_bug.cgi?id=688779
Mechanically transform the event processing of mutter to care
about XI2 events instead of Core Events. Core Events will be left
in the dust soon, and removed entirely.
https://bugzilla.gnome.org/show_bug.cgi?id=688779
This removes some duplicate event type checks, and will make
the code cleaner in the future when we want to make the grab_op_event
handler take an XIDeviceEvent directly.
Based on a patch by Owen Taylor <otaylor@fishsoup.net>
https://bugzilla.gnome.org/show_bug.cgi?id=688779
In order to make the XI2 handling easier on us in the future, we now
split input events from non-input events. This will allow one code path
to use XIEvent, and the other to use XEvent in the future. This commit
has involved plenty of indenting changes, so it's better seen with
git diff -b or &ignorews=1
https://bugzilla.gnome.org/show_bug.cgi?id=688779
Currently meta_display_get_tab_list() will only return windows on
a single workspace. Make the workspace parameter optional to allow
requesting windows from all workspaces.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents
to determine the KeyBindingAction the event would have triggered and
run our own handlers (ugh).
Instead, provide a hook to allow the compositor to filter out keybindings
before processing them normally, regardless of whether the compositor
holds a grab or not.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
The X server sends a XkbNewKeyboardNotify event for each keyboard
device when a new keyboard description is loaded. These days a typical
computer has several keyboard devices, e.g. xinput on this laptop
lists 8. Since the work we do on these events is relatively expensive
and we are only really interested in changes to the virtual core
keyboard we can skip other devices' events to cut on needless work.
https://bugzilla.gnome.org/show_bug.cgi?id=674859
Moving focus immediately on crossing events as we currently do
in focus-follows-mouse mode may trigger a lot of unwanted focus
changes when moving over unrelated windows on the way to a target.
Those accidental focus changes prevent features like GNOME Shell's
application menu from working properly and are visually expensive
since we now use a very distinct style for unfocused windows.
Instead, delay the actual focus change until the pointer has stopped
moving.
https://bugzilla.gnome.org/show_bug.cgi?id=678169
As plugins can now define their own keyboard shortcuts via
meta_display_add_keybinding(), it makes sense for them to
expose those shortcuts to System Settings, so add some API
to set the properties gnome-control-center uses to pick up
wm keybinding settings.
https://bugzilla.gnome.org/show_bug.cgi?id=671010
We may not show the backtrace, but it's prohibitly expensive to generate,
so don't. If someone wants a backtrace they can use the appropriate G_DEBUG
environment variable plus GDB.

Require the headers for "XFree86" Xinerama to be present at compile
time. The older "Solaris" Xinerama is only needed for versions of
Solaris where Mutter is unlikely to work. Solaris 10 and 11 include
the XFree86 Xinerama libraries, and apparently that's the only version
that will actually work for Solaris 11, which uses Xorg.
https://bugzilla.gnome.org/show_bug.cgi?id=674727
Currently pressing the overlay key only triggers the overview if
no other key is pressed between KeyPress and KeyRelease. Extend
this logic to pointer events, so that KeyPress + ButtonPress actions
are treated explicitly different from "pure" overlay key presses.
In particular, this change allows to re-use the overlay key as mouse
button modifier.

This is a new value, not associated with any keybindings, useful
when the WM needs to order the applications by last-interaction,
taking into account all windows.
https://bugzilla.gnome.org/show_bug.cgi?id=667552
Some modifiers like NumLock and ScrollLock don't make sense in
keybindings, which is why we ignore them when matching keybindings
to events. We should do the same in Javascript, so add an accessor
function.

When meta_display_unmanage_window_for_screen() is called, it gets a list
of windows and iterates over them and unmanages them, but unmanaging a
window with attached modal dialogs also unmanages those attached modal
dialogs (in the normal case, temporarily), so we need to guard against
such cases by ref'ing the windows in the list and checking if they have
already been unmanaged.

meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.

https://bugzilla.gnome.org/show_bug.cgi?id=597190
Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.
